What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Baltic Aquascaphe Dual-Crown

The Baltic Aquascaphe Dual-Crown is widely praised for its modern take on a vintage Super Compressor design, featuring a legible internal bezel and a clean, balanced dial. Reviewers consistently highlight its excellent wearability, attributed to its 39mm case size with elegant proportions and slender flanks. The case finishing, including polished chamfers and a unique brushed bezel top, is also a noted strength. It is powered by the Miyota 9039 movement, offering 200m water resistance. One reviewer found operating the internal bezel crown to be a fiddly and slower experience compared to standard dive bezels, and another noted the domed sapphire crystal can be somewhat reflective. Prices ranged from €550 during pre-order to €780 retail. Overall, reviewers rate the Baltic Aquascaphe Dual-Crown highly for its charming vintage-inspired design and excellent value.

From video reviewers

The watch's bezel action is smooth and precise, making it easy to turn. A weakness of the watch is its lume, which is somewhat lacking in low-light conditions. Reviewers disagree on the lug-to-lug fit, with one reviewer calling it comfortable for everyday wear and the other describing it as relatively slim for smaller wrists.

Sinn U18

The Sinn U18 is praised for its unique deep blue/green dial with three-dimensional oxygen bubbles that change with light, and its comfortable, easily adjustable bracelet. Owners find the watch stunning and a piece of history, appreciating the refined hands. The Sinn U18 features a 44mm, 15.5mm thick case made from German submarine steel, offering a 2000-meter dive specification and Sinn's Ar-Dehumidifying technology, powered by a Sellita SW300-1 movement. The case thickness is apparent, and the watch comes as a complete set with box and papers for $3,000-$3,680. On balance, owners and reviewers rate the Sinn U18 highly for its striking dial and robust build.
